Barcode Scanning? - ShaneStump - 05-23-2020
Howdy All!
I have been trying to get my customers to use barcode scanning for years on e-tickets, printed tickets, etc and I never could get a taker.
Now with the Coronavirus and the need for touch-less / less contact, everyone wants it yesterday.
In the past, I tried using CGDevTool's mask edit control, and to be honest, I don't remember how it worked as the customer I did it for 5+ years ago didn't have a very good Internet connection and so I abandoned it (and I don't use CGDevTools anymore with IW).
In a perfect world, I would implement this as a FireMonkey app for Android/IOS/Windows but I need it yesterday.
I can take VCL versions out of my main application, create a new REST api for validation, and create a stand-alone Windows application. Problem with this is that there aren't many good / affordable Windows tablets.
In 2020, the obvious solution would be for to create an IW page accepts a barcode and sends it to the server for validation.
The problems I have with this method are:
1) I am NOT a javascript / jquery expert,
2) Keeping the focus in the input control and having the barocde parsed realtime (i.e. in javascript)
I have seen javascript libraries out there and I was wondering if anyone has or knows of a IW component that wraps one of these javascript libraries into something usable / useful for the rest of us?
I am looking for something like:

All the best,

JNP I think did bar codes.. I will ping him.
RE: Barcode Scanning? - kudzu - 05-23-2020
Also how are you needing to scan the bar codes? Upload? Camera? Bar code wand?
RE: Barcode Scanning? - ShaneStump - 05-23-2020
To be honest, the reason I want to use an IW solution if possible is it would allow my customers all the above (I am guessing).
For my purposes, I just need a 'scan bar code dialog to pop-up', scan the bar code, and call an event for processing with the barcode text (not the image).

I just found this and tested it with its example and it works:

I just need to figure out how to connect all the dots on one of these solutions.
I will have a look a the youtube video (thanks)!

I saw that video earlier but it didn't have any code behind it.
Do you have a simple IW app that shows how to integrate / use it in your IW application?
Thanks in advance,

I quasi got the method on this page working:
https://www.sitepoint.com/create-qr-code-reader-mobile-website/
I just need to see if I can spruce it up and add a few event handlers of my own.
I will keep everyone posted as I think this might be useful to others.
All the best,

Maybe a demo app for the site is in order!

Dan,
I will see what I can do once I finish getting it wrapped around my head.
These days I basically write a class that wraps the functionality and then sub-class a TIWBS4Label at run-time.
All the best,
Shane
